The Science of Ancestral Medicines: What Modern Research Says About Them?

Ancestral medicines have always been surrounded by a mix of mystery and reverence. Indigenous peoples and spiritual traditions worldwide have used plants and healing rituals for millennia, passing down knowledge from generation to generation. But what about modern science? What do recent studies say about these medicines? Are they just beliefs, or is there a scientific basis for their effects?

Today, we will explore what science has discovered about some of the most important ancestral medicines – such as Ayahuasca, Rapéh, Kambô, Sananga, and Mapacho – and how they can help us on the path of healing and self-knowledge.

1. Ayahuasca: The Tea of Consciousness Expansion

Ayahuasca is one of the most well-known sacred medicines of the Amazon. Made from the combination of Banisteriopsis caapi (vine) and Psychotria viridis (leaves containing DMT), this brew has been used by shamans for centuries for spiritual, healing, and visionary purposes.

Scientific studies confirm that Ayahuasca has profound effects on neuroplasticity. Research from the University of São Paulo shows that the alkaloids in Ayahuasca can promote the growth of new neural connections, which can be beneficial for treating depression, anxiety, and post-traumatic stress disorder (PTSD).

Moreover, many people report experiences of deep introspection and emotional healing when taking Ayahuasca, accessing repressed memories and gaining a better understanding of their emotions and traumas.

2. Rapéh: The Breath of the Earth

Rapéh, one of the most revered medicines among Amazonian tribes, is a sacred blend of finely ground tobacco and other medicinal herbs applied through the nostrils. Its ceremonial use aims to align energies, bring mental clarity, and cleanse energetic and physical impurities.

Science has already demonstrated that unprocessed tobacco, used in Rapéh, is very different from industrialized tobacco. The nicotine in it acts as a cognitive stimulant, improving memory, concentration, and even offering neuroprotection against neurodegenerative diseases such as Alzheimer’s.

On an energetic level, research on the psychological effects of Rapéh indicates that it can help with grounding and emotional regulation, aiding in focus and mental balance.

3. Kambô: The Vaccine of the Forest

Kambô is a secretion extracted from the Phyllomedusa bicolor frog, used by many Amazonian tribes to strengthen the immune system, cleanse negative energies, and enhance physical endurance.

Science has explored the bioactive peptides present in Kambô, which have antimicrobial, analgesic, and anti-inflammatory properties. Studies from the Federal University of Rio de Janeiro (UFRJ) have shown that these peptides may help destroy cancer cells and regulate blood pressure.

Kambô application is intense and causes a strong detox reaction, including sweating, vomiting, and increased heart rate. However, its purifying and strengthening effects are widely recognized among those who use it regularly.

4. Sananga: The Spiritual Vision

Sananga is an eye drop made from the roots of the Tabernaemontana undulata plant, used by tribes such as the Huni Kuin to enhance vision, both physical and spiritual.

Research suggests that the alkaloids present in Sananga have anti-inflammatory and analgesic properties, potentially aiding in the treatment of eye diseases such as glaucoma and cataracts.

Many reports also indicate that Sananga can help remove energetic and emotional blockages, promoting greater mental and spiritual clarity.

5. Mapacho: The Sacred Tobacco

Mapacho, also known as wild tobacco (Nicotiana rustica), is used by shamans in rituals of cleansing and spiritual protection. Unlike commercial tobacco, it is pure and has a much higher concentration of beneficial alkaloids.

Studies show that Mapacho has antibacterial and antifungal properties, acting as a natural purifier. In a spiritual context, it is believed that Mapacho smoke creates a bridge between the material and spiritual worlds, aiding in connection with higher entities.

Science and Spirituality Can Walk Together

What was once considered “superstition” is increasingly being proven by science. Ancestral medicines carry not only physical healing but also a profound impact on mental and spiritual well-being.

Modern science is just beginning to understand what ancestral peoples have known for millennia: healing goes beyond the body and mind, reaching energetic and spiritual dimensions.

By opening ourselves to this knowledge, we can find more natural and integrative ways to heal ourselves and connect with the world around us. After all, the wisdom of the forests and ancient peoples has much to teach us.
